Congratulations are in order to Vargas Turbo Tech as well as Cobb tuning and ProTuning Freaks for raising the bar as to what the BMW N54 inline-6 twin turbo motor is capable of. There are two platform records here the first of which it is important to note was achieved without methanol injection. There are certain tuners on the N54 platform that mask their ability to upgrade and control the stock fueling system and any fueling issues are "solved" by dumping in a ton of methanol.

Well, with no meth and the cars own fuel system (with High Pressure Fuel Pump tweaks courtesy of Vargas Turbo Tech) responsible for all the fueling 673 wheel horsepower was achieved in STD correction on a Dynojet. That is a record for horsepower on the platform without methanol injection and was done with a blend of MS109 fuel and 93 octane.

Meth injection was then added and the figures rose to 693 wheel horsepower. If more time was available for the parties involved including Josh at Cobb as well as Jake and Dzeeno at ProTuning Freaks the 700 wheel barrier likely would have been crossed. This will happen sooner rather than later now but this is still a major milestone and a new era the N54 is entering. The motor is finally starting to mature and although it is not on a comparable power level yet with the top BMW aftermarket options this is a huge step step forward for a platform that spent considerable time in limbo due to fueling and tuning issues.

It must be satisfying for all involved especially Vargas Turbo who was doubted by many early on due to being a fresh entrant on the N54 tuning scene with many fanboys blindly following another tuner providing a turbo upgrade. Vargas Turbo Tech, Cobb, and PTF have surprisingly quickly surpassed the results from a competing turbo kit that uses a single turbo setup and have done so without relying on meth injection band-aids. A true fueling upgrade is here as well as a turbo upgrade making some serious power and setting the standard.

Congratulations and much respect to all the parties involved, dyno graphs and videos are below.

There's no way to 100% confirm what the octane was because 109 was mixed with whatever, unknown amount of 91 in the tank, but it was def over any standard pump gas & shy of true Race Gas (100+).

I think it's great & all that we're not hitting 700 WHP on a completely stock motor with a GTX Twin Turbo upgrade, but what's really going to make this an appealing upgrade (besides the price & retaining the OEM DME turbo setup so you can use any tune) is reliability and after prolonged use, if the OEM N54 internals can keep up.

Are any of the tuners/vendors going to be opening up the motor after xxxx Miles to see if the rods & pistons are handling the power well, or are we going to go the "we'll known when something breaks" route?

Well if it makes you feel any better, we have almost 5K miles on the car and have done Hundreds I mean HIGH hundreds nearing a thousand WOT pulls in 3rd, 4th, and 5th. The worst I had seen is a boost hose slip a bit and need a clamp adjustment, and a shredded Serpentine belt. We threw at least 200 runs at it this weekend. the last 50 or so 28 psi and over. The car never even puffed blue smoke once, nor did anything weird. The tunes we are running are safe and we get there very slowly. The reliability will continue to be proven but so far its more then proven itself, as we are pushing past where anyone has on boost, and power levels.

Every time the motor hits some higher number some retard has to say this. Oh yeah it's SUCH a SUPRA. No it isn't, it never will be, get over it. It's an N54 not a 2JZ and the S54 is closer to being a 2JZ than the N54 ever will be. For $#@!s sake...
